What the Heck are they thinking?

I drive a motorbike- or I did until the weather turned nasty. I have to concentrate fully on the road - wondering which drivers are going to cut me off or decide they really want my lane and I can just bloody well move out of their way since they are bigger than me.

Just this past week I ran into (not literally) three people texting while they were driving. One of them had his hands through the steering wheel so he could drive with his forearms while he two handedly texted on his blackberry. One lady was 'only' texting one handedly since the other one was holding her cigarette - perhaps she was driving with her knees as I didn't actually see any part of her upper appendages on the steering wheel.

Its too bad stupidity isn't immediately painful. Imagine what the world would be like if the second you had a stupid idea a 2x4 appeared out of thin air and hit you solidly in the middle of the forehead. "I think I'll drink and drive" - WHAM! "That guy I met last night at the bar seems like such a wonderful guy. Since his wife is such a frigid bitch I'll sleep with him to ease his pain" - WHAM (twice since this is stupid x2 - 1- he's not a great catch or he wouldn't be plying his sob story in the bar and 2 - even if his wife is a frigid bitch - sleeping with him will do nothing but cause you pain. "I'm going to tell my boss what I really think of him" - WHAM.

You get the idea - any other suggestions for stupid actions that deserve a WHAM?
